Can you recommend a time-travel novel where the male protagonist is a prince but he plays dumb?

😋I recommend the following two novels to you, both of which are about traveling through the ancient times. 1. "Stupid King, Look Over, Alluring Killer Concubine": After the killer was chased out by the organization as a waste, the waste father, the waste woman, and the fighting aunt did not show any mercy. She was living a carefree and happy life, but everything was ruined by a fool named Bai Juanyong. 2. [Reporting to Medical Consort, His Highness is acting dumb again]: The female protagonist who died suddenly in the laboratory, traveled back to ancient times, and was engaged to a silly prince. Every day, he pestered her to kiss, hug, and lift her up high. He only had eyes for her! The female protagonist had a Holy Doctor in her left hand and a Poison Master in her right hand. However, her young paparazzo was so stupid that no amount of medicine would work! The female protagonist finally realized that his highness was playing dumb. I hope you like this fairy's recommendation. Muah ~😗
